Detroit Rises from the Ashes

On the flight home from ACI’s 2014 National Home Performance Conference, I read Charlie LeDuff’s Detroit: An American Autopsy. It’s a gritty, sad story about the decline of one the greatest U.S. industrial cities. It was fitting that ACI’s conference was held in Detroit–thanks to the growth of the auto and wartime industries in the early 20th century, Detroit was the birthplace of the U.S. middle class. But according to LeDuff, Detroit, which “once led the nation in home ownership,…

More HERS Ratings Expected in 2015

The Residential Energy Services Network (RESNET) announced its collaboration with the International Code Council last week in an effort to help home builders transition to the new 2015 International Energy Conservation Code (IECC). In the upcoming version of the residential building code, RESNET's HERS Index will be an optional compliance path — some people are saying that this compliance path represents the most significant change coming to 2015 IECC

Strategies To Keep Millennials At Their Peak Performance In A Home Performance Company

Let me first start by confessing my guilt... Guilt for being bored easily, guilt for wanting praise, even if it is a pat on my own back for an achievement... Guilt for being a millennial... On the other hand I enjoy working in teams and I encourage frequent communication between all team members from admin staff to auditors, sales staff and crew members to improve our workflow. Yes, I am a millennial, but let me add that there is nothing that makes me cringe more than the excuses I get from…

Off-the-Shelf – LEED & National Green Building Standard as Residential Building Code

Cities grafting green-building certifications like LEED into commercial building codes is nothing new, and a number of places like Dallas, Atlanta, Boston and Scottsdale have had such requirements in place for a decade or more.

'Oh Wow' Tech and Trends from Energy Efficiency Insiders at Washington, D.C. Gathering

Brainy light bulbs. Refrigerators that heat dishwasher water. Elevators that use no more energy than toasters. These are just a few of the “Oh Wow’ topics last week at the annual EE Global conference.

But it was growth in cities – and their buildings – that was clearly on the minds of industry leaders, 500 in total who gathered at the Washington, D.C. event, sponsored by the Alliance to Save Energy.

The US spends $432 billion per year on energy for buildings –…

What Ballerinas and EPros Have in Common...

I'm pretty new to this whole industry... And by new I mean that the jumble of acronyms and terminology are still enough to leave me a bit dazed when some well meaning individual spurts off several in one sentence.  

Home efficiency is not a field I ever could have imagined being involved in.  By training, I'm an a ballerina.  I've danced since I was three, trained in NYC, graduated from a conservatory... the works. And yet here…

Top 5 A/C Code Requirements not Enforced

  This list does not represent the entire code, or even all municipalities.  Everyone knows those towns that will hit you on every piece of the local code requirements, word for word from the text.  But, don't be surprised when code officials, both building and mechanical inspectors, start failing permit inspections for these previously rarely enforced portions of the code!  Are you going to wait until enforcement, or lead the industry in doing what the minimum is required by…

Residential Green Valuation Tools

Ever wonder how appraisers develop value of houses with green or energy efficient features?  Residential Green Valuation Tools was published last month by the Appraisal Institute.  The 189-page book has 13 chapters that address the most often asked questions about the valuation process and green building.  As the author of the book, I found the challenge of writing this book a great learning and…

I survived my first ACI

I did it. I survived my first conference in this industry, the 2014 ACI National Home Performance conference in Detroit.



When I joined The Energy Conservatory in June 2013 I was brand new to this industry. Before TEC I didn’t even know this industry existed, let alone what a blower door was. To help me learn all of this building science geekiness I decided to take BPI’s Building Science Principles course and exam. I read the book twice, and then took the exam, which I passed! I…

Everyone Knows You Except for Your Electric Utility

Netflix, you were right. I liked Downton Abbey. And thanks, Amazon I do want to read Michael Lewis’ new book. I still can’t figure out how Google knows I have a new dog.

Even if at times it feels a bit eerie, such ‘consumer-of-one’ marketing is a convenience many of us have come to appreciate. And it’s an approach now embraced by most major retailers.

The exception? You’ve guessed it: the ever-old fashioned electric utility.

But…
